Murphy co-starred in "You'll Like My Mother," playing a secretive woman who fears a character played by Patty Duke will take the family fortune. The film was shot at the Congdon estate in February 1972 and was screened at the mansion last month in an event featuring Duke.

In a Tweet, Duke called Murphy a brilliant actress and said it was wonderful to know and work with her.

Murphy was active in the industry for more than six decades and had dozens of roles. She's perhaps best known for playing Miss Maudie in 1962's "To Kill a Mockingbird" and won a Primetime Emmy for her portrayal of Eleanor Roosevelt in 1976.

This time last year the Apostle Islands Ice Cave season was about to wrap up, but this year, it's just getting started, and the shorter season had crowds flocking to the attraction for its opening weekend. Just days ago, park officials gave the okay for the ice caves to open up to the nearly 11,000 visitors who came over the weekend.
